22. The degree for each interior angle would be 125°.
An angle can be up to 180°(straight line) for a shape such as a polygon.
23. The answer would be a scalene triangle. Not all the angles are the same degree.
21 I'm not sure:(
3d=12
This should be your equation
And if it is asking for the answer it would be 4
I hope this answer helps!
Answer:
<70.71, -70.71>
Step-by-step explanation:
The vector has a module of 100 and a angle of -45° (negative because it is below the horizontal). So, to find its components, we need to use the sine and cosine relation of its angle:
horizontal component = module * cos(angle)
horizontal component = 100 * cos(-45)
horizontal component = 70.71
vertical component = module * sin(angle)
vertical component = 100 * sin(-45)
vertical component = -70.71
So the vector in the component form is <70.71, -70.71>
The negative sign of the vertical component means its direction is downwards.
The answer should be 21 hope it helps
